Hobbyist mines Bitcoin block after beating 18,000-year odds with a $250 device
Somewhere out there, a hobbyist plugged a device roughly the size of a coffee mug into their wall, connected it to the internet, and won the Bitcoin mining equivalent of Powerball. Using a Bitaxe ASIC miner that retails for around $250, a solo miner successfully found a complete Bitcoin block around July 12, 2026, earning the full 3.125 BTC subsidy plus transaction fees.
The expected wait time for a device like this to mine a block? Approximately 18,000 years.
The math that makes this absurd
The Bitaxe is a compact, open-source ASIC miner that hums along at roughly 1 to 1.2 terahashes per second. It draws between 15 and 25 watts of power, which is less than a light bulb.
To put the odds in sharper relief: a similar setup running at 6 TH/s, which is already several times more powerful than the winning device, would have daily odds of approximately 1 in 180 million. The miner that actually hit the block was working with even less firepower.
The block reward of 3.125 BTC translates to somewhere between $200K and $270K depending on the price of Bitcoin at the time.
How solo mining actually works at this scale
Solo mining doesn’t mean a miner is completely alone in the wilderness. Hobbyists typically connect to solo mining pools like CKPool or Braiins Solo, which handle the infrastructure of submitting valid blocks to the network. The critical difference from traditional mining pools is that the miner who finds the block keeps the entire reward, rather than splitting it proportionally across all participants.
Multiple solo mining successes by hobbyists running sub-10 TH/s miners have been reported between 2025 and early 2026.
Why the big miners aren’t worried
Large-scale mining operations dominate Bitcoin’s total network hashrate by an overwhelming margin. Industrial facilities running thousands of next-generation ASICs are the ones securing the network and collecting the vast majority of block rewards.
Bitcoin’s price didn’t move because of this event. No mining company’s stock reacted. The network kept producing blocks every ten minutes on average, as it always does.
What the event does illustrate is something more fundamental about Bitcoin’s design. The protocol is genuinely permissionless. A $250 device has the same theoretical chance per hash as a $250 million mining facility. The facility just gets astronomically more hashes per second.
What this means for the curious and the cautious
Running a Bitaxe costs almost nothing in electricity. At 15-25 watts, you’re looking at maybe a few dollars per month depending on your local power rates. The device itself is a one-time $250 expense.
The real takeaway for anyone considering this path: treat it like entertainment spending, not an investment thesis. At 1 TH/s against the current network difficulty, the expected wait time to mine a block is approximately 18,000 years. But as this hobbyist just demonstrated, statistics describe populations, not individual outcomes.

It takes an average of 4.8 years from finalizing investment to starting construction of a data center project, and an additional 2.6 years from construction start to becoming operational. Servers usually cannot be installed until after the building structure and racks are completed. For trade partners such as Taiwan (China), South Korea, and Mexico who rely on US data center supply chain demand, the inertia in construction timelines provides at least a one- to two-year buffer for future exports.
Federal Reserve Major Debate: When Should the Tenure of “Number Three” Williams End?
The main point of contention is whether Williams should step down in June 2028, upon completing a full 10-year term, or in June 2027, when he reaches the mandatory retirement age of 65. Analysts point out that the Federal Reserve Board holds ultimate discretion; if he leaves early, Fed Chair Waller would be able to assert greater control over the appointment to this critical position. However, forcing Williams to shorten his term could easily be interpreted as political manipulation. Williams himself is expected to serve until June 2028.
